  • U.S. Senate: A special election is being held to fill the Senate seat vacated by John McCain (R) upon his death from cancer on August 25, 2018. The seat is currently held by Martha McSally (R), who was appointed by Arizona Gov. Doug Ducey (R) to replace Jon Kyl (R), the governor’s first appointee. The winner of the special election will serve the remaining two years of McCain’s term.
  • U.S House: All nine of the state’s House seats are up for election.
North Dakota
  • No U.S. Senate seats are up for election. North Dakota’s one at-large U.S. House seat, currently held by Kelly Armstrong (R), is up for election.
  • U.S. Senate: The Class II Senate seat currently held by Jim Inhofe (R) is up for election.
  • U.S. House: All five of the state’s House seats are up for election.

North Dakota’s primary is scheduled for June 9, Oklahoma’s primary is scheduled for June 30, and Arizona’s primary is scheduled for August 4. The general elections in all three states are scheduled for November 3, 2020.
